Why is the Great Red Spot on Jupiter shrinking?

This may be due to the intensity of the storm, but one of Jupiter's most famous features may be the swirling vermilion storm on the south side of the equator.

Back in 1979, two Voyager space probes passed by the massive planet Jupiter, giving researchers the opportunity to measure the red dot. Researchers of this new project want to know if its thickness has changed since then. But because the atmosphere is opaque, it is impossible to measure spot thickness directly, forcing them to use indirect means, such as building mathematical models and numerical simulations of a vortex in a plexiglass tank filled with salt water.

Jupiter's Great Red Spot has always been the object of curiosity and careful observation by professional and amateur astronomers. In recent years, this has become apparent, with Jupiter's Great Red Spot shrinking, once about three times as wide as Earth's, now only twice as wide as Earth's. Because of this, some in the space science community are beginning to wonder if this Great Red Spot storm is weakening and if one day it will disappear completely.

In the new study, the researchers sought to better understand the thickness of Jupiter's Great Red Spot.

By comparing and combing through the results of their research, a consensus was reached: the Great Red Spot is about 170 kilometers thick, and its results are in good agreement with the measurements of the Voyager probe, indicating that the thickness of Jupiter's Great Red Spot has remained relatively stable. The next step in the study is to compare the results with data from NASA's Juno space probe, which orbits Jupiter every 53 days.

Jupiter's dynamics shape Jupiter's cloud shape, but this natural observance is still largely unknown. Therefore, uncovering the potential three-dimensional flow of clouds is the main goal of NASA's ongoing Juno mission.

In this study, laboratory experiments complemented by theoretical and numerical analysis were used to study the dynamics of Jupiter's vortex and to determine the general balance of forces that form Jupiter's Great Red Spot-like shape. The study defines the scaling law of Jupiter's horizontal and vertical aspect ratios as a function of rotation, stratification, and zonal wind speed with the environment. For the Great Red Spot in particular, the horizontal dimension of the study** coincides with measurements at the cloud level since the Voyager mission in 1979.

At the same time, the thickness of the large red spot is also **, which cannot be directly observed. Despite the observed horizontal contraction, it has surprisingly remained unchanged, and the results are now awaiting comparison with the upcoming Juno observations.

"Although we don't know all the energy**, or how the erythema loses energy, these conditions can break the erythema energy flow balance over a period of time, which may be the reason why the erythema continues to shrink with less energy input and the storm slowly gets smaller and smaller," the scientists said.

The Great Red Spot on Jupiter is actually the effect of the sun's infrared radiation on Jupiter, and the Great Red Spot on Jupiter is shrinking, indicating that the sun's infrared force on Jupiter is decreasing.

Because fission and fusion took place. When the body undergoes fission and great changes, energy is released through the reduction of matter, so that the Great Red Spot on Jupiter can be seen gradually shrinking.

Jupiter. It is a gas planet, the Great Red Spot.

The root cause of Jupiter's poor rotation – not only does it form a great red spot, it also forms several cloud bands and several "small red spots" and "great white spots".

Jupiter's Great Red Spot is located at 23 degrees south latitude of Jupiter. The Great Red Spot is a giant vortex of gas. The diameter of the Great Red Spot is larger than the diameter of the Earth, about twice the diameter of the Earth.

To the great surprise of all astronomers, Jupiter's Great Red Spot can appear all the way in the same location and can rotate counterclockwise at a steady rotation speed for one week for six Earth days. In addition, it has been around for more than 300 years since the discovery of the Great Red Spot.

Jupiter rotates clockwise from west to east. Jupiter's rotation period is 9 hours, 55 minutes, and 30 seconds. Jupiter's rotation period is determined based on the Great Red Spot and Jupiter's rotation period. Jupiter's equatorial clouds move faster, while Jupiter's polar clouds move more slowly.

Jupiter's Great Red Spot is reddish-brown because Jupiter's lower atmosphere contains a lot of sulfur and ammonia particles. Because the mass of sulfur and ammonia particles is higher than that of water vapor.

Composition of the cloud is large.

So covered by clouds. When Jupiter's atmosphere forms a gas spiral, the gas spiral absorbs sulfur and ammonia particles under the clouds, giving Jupiter's Great Red Spot a reddish-brown color.

The size of the large red spot is decreasing. Mathematical models.

It is estimated that storms are stable and may become a permanent feature of the planet. However, since it was discovered, there has been a noticeable decrease in its size. Initial observations in the late 19th century showed that it had a circumference of nearly 41,000 km.

To 1979 Traveler.

At the time of observation, the storm was 23,000 km long and nearly 13,000 km wide. Hubble's observations in 1995 showed that its size had decreased again to 20,950 km, and in 2009 it had reached 17,910 km. By 2015, about 16,500 km of storms had been measured, and the rate was decreasing at a rate of 930 km per year.

Jupiter's Great Red Spot is one of the largest storms in the solar system, its largest area can put four Earths in it, this storm has been raging for hundreds of years, from its evolutionary trend, it is in the process of shrinking or even disappearing, but as the saying goes, the back waves of the Yangtze River push the front waves, and the front waves die on the beach, when the Great Red Spot of Jupiter disappears, will there be a new giant storm to replace it? In fact, there is a huge storm forming right now, and its storm range can already put down a single earth.

As it stands, it is likely to be, because it is also the end result of a planet's atmospheric cycle, which, combined with its own rotation, leads to a more complex atmosphere of Jupiter. And the atmosphere is divided into rotating straight lines, and so on. Under these conditions, the gravitational pull of the sun creates a cyclone, which is the formation of a large red spot, but this will disappear someday in the future.

But it will take a long time! Yes, like sunspots in the sun, it will repeat.

Yes. This is an inevitable consequence of Jupiter's atmospheric cycle. The rotation and revolution complicate the movement of Jupiter's atmosphere, in which there must be a rotation of gases, resulting in a cyclone, the Great Red Spot.

A cyclone is the equilibrium state of a planet's atmosphere, just like the revolution and rotation of a planet. Jupiter is the closest and largest planet to Earth, and due to its greater mass than Earth, it has the most obvious impact on Earth! The spots that appear or disappear are sure to cause changes in the earth!

It'll be gone. Due to the rapid changes in Jupiter's atmosphere, the storm has no food, and eventually leads to continuous shrinking, the other is that due to the storm swallowing up the surrounding chemical gases too much, resulting in chemical reactions that make the scope of the storm is getting smaller step by step, compared to the big red spot 2000 years ago, it can swallow 3 Earths, and now it is 1 Earth, scientists believe that the big red spot will not disappear so quickly, we can see it at least in the next 2000 years, So it will remain the first in the solar system for 2,000 years, and after that maybe it will disappear completely.

This is because Jupiter's Great Red Spot has slowed down again this year, so the Red Spot has become smaller and smaller.

Because the storm on Jupiter is decreasing and may be disappearing soon, the red spot is getting smaller.

It's Jupiter that keeps turning, and over time, it's been changing.

Hello, it's a pleasure to answer the <> of Jupiter's Great Red Spot

Hello Jupiter's Great Red Spot is a characteristic sign of Jupiter's surface, the largest storm cyclone on Jupiter, about 25,000 kilometers long, 12,000 kilometers up and down, rotating in a counterclockwise direction every 6 Earth days, often rolling up to 8 kilometers of cloud towers. Since the storm was first observed by astronomers in the 17th century, the Great Red Spot has been around for at least 200 to 350 years. It has changed color and shape, but it has never completely disappeared.

Hello, it's a pleasure to answer Jupiter's Great Red Spot pro-<>

Hello Jupiter's Great Red Spot is a characteristic sign of Jupiter's surface, and is the largest epochal storm cyclone on Jupiter, about 25,000 kilometers long, spanning 12,000 kilometers up and down, rotating in a counterclockwise direction every 6 Earth days, often rolling up cloud towers up to 8 kilometers high. Since the storm was first observed by astronomers in the 17th century, the Great Red Spot has been around for at least 200 to 350 years. It has changed color and shape, but it has never completely disappeared.

The Great Red Spot in Jupiter's atmospheric field is a vigorous anticlockwise downdraft that contains a large amount of red phosphide and is dark brown. Jupiter's Great Red Spot's location is not fixed, but is constantly moving. Jupiter's Great Red Spot is roughly located at 23° south latitude, and its north-south width is often maintained at 14,000 km, with its length varying from east to west at different times, reaching about 40,000 km at its longest and generally at 20,000 to 30,000 km.

In the center of the Great Red Spot there is a small particle, which is the nucleus of the Great Red Spot, which is about a few hundred kilometers in size. This nucleus is immobile in the surrounding anticlockwise vortex motion. The Great Red Spot has a long lifespan and can last for hundreds of years or more.

According to the observations, scientists found that the most obvious red region in Jupiter's Great Red Spot confirms the theory that there is a hot core inside the Xunxiang cold storm system. The dark lines at the edge of the storm in the observation show that the gas released by the storm eruption is spreading into the interior of the planet.

Hello, friend, do you have any questions?

A series of images taken between May and June 2019 captured the reddish extension, known as "flaking," observed on the eastern side of the Great Red Spot. New research shows that the storm itself is still intensifying despite the apparent shrinking of the clouds at Jupiter's Great Red Spot. Jupiter's Great Red Spot represents the most powerful storm in the solar system.

Early studies have shown that storms have been declining since at least the 19th century, and researchers at the University of California, Berkeley, at a meeting of the American Physical Society's Fluid Dynamics Section on Nov. 25, argued that there was no evidence that the vortices driving cloud formation were changing. "I don't think its fate was ever bad," said Philip Marcus, a professor of fluid dynamics at the University of California, Berkeley, saying in a statement released by the association that it was more like Mark Twain's comment: Reports of [storm's] deaths were greatly exaggerated.

However, the observer did not see the storm directly, only the visible clouds above it. He and his colleagues believe that the "flaking" observed around the storm is a natural result of storm interactions, rather than a sign that the Great Red Spot storm itself is weakening.

is in the form of a small storm that rotates in opposite directions approaching the Great Red Spot, a stagnation point. Then, when a small storm in the same direction as the monster storm approaches, its clouds are shattered and peeled off in reddish extensions, as observed on the east side of the storm this spring, Marcus said, and his research focuses on swirls, the hydrodynamics of waves, turbulence and hydrodynamic stability.

These are very normal health activities for Red Dot and his colleagues," Marcus said at a press conference held at the association's meeting.

In addition, Marcus said, "I think that unless there is some kind of catastrophic change in Jupiter, it will continue for an uncertain future until the jet stream changes, so I think it could last for centuries." "Sure, I might just give it a kiss of death, and it might unravel next week, but that's how science works.

Jupiter's red spot is one of the most prominent features of the solar system. It was a massive storm three times the size of Earth. Ever since astronauts first saw it with a telescope, it has been raging around the top of Jupiter's clouds.

The material known as the Great Red Spot is actually a storm formed by a high-pressure anticyclone. The storm is rotating around 22 degrees around the week. Astronauts recognize that this is the deeper red color that comes from how to get sulfur and ammonia particles from the deeper depths of Jupiter's atmosphere.

These chemicals start out black and then brighten when they are exposed to sunlight. Small storms on Jupiter are usually white and darken as they get bigger. Formation of erythema jr

The storm changes from white to red as it grows large and violent.

Astronauts aren't sure if Jupiter's red spot is permanent or temporary. It has been visible since astronauts began to observe it carefully since the 17th century. And it is still visible on Jupiter.

Some inferences ** that this storm may look like an eternal fixture on Jupiter. You can still see this erythema with a small telescope that is more than 15 cm (6 inches) vertical.

The edge of the erythema is spinning at a speed of about 360 km h (225 mph). The size of the whole point varies from 24000kmx12000km to 40000km in width. In this storm, two or three earths can be plugged.

The actual edges of the storm are up to 8km apart beyond the cloud summit perimeter.

Huge red spots and other swirls.

As Voyager 1 time passes, we can see the movement of the atmosphere and the circulation of the Great Red Spot. Taken every 10 hours**, over 32 days. Watch the entire footage.

The most well-known phenomenon of Jupiter is the Great Red Spot, a persistent anticyclonic storm larger than Earth, which is located 22 degrees south of the equator. It has been known to have existed there since at least 1831, possibly in 1665. Judging from the Hubble Space Telescope's **, the two red spots are close to the giant red spots.

The storm is so large that it can be seen through a telescope with an aperture of 12 cm or larger. The oval-shaped object rotates counterclockwise at a six-day cycle. The maximum height of the storm can reach 8 km above the surrounding clouds.

Relevant knowledge. The Great Red Spot is a huge anticyclonic storm that has existed for a long time at 22° south of Jupiter's equator. It has been continuously observed for 189 years, starting in 1830.

However, there have been records of observations between 1665 and 1713, and it is possible that the same storm has been in place, indicating that it has been in existence for at least 350 years. Such storms are not uncommon in the atmospheric disturbances of the Jupiter-like planets.
